SYSABEND DD statement
Produces a dump of user and system areas; this dump contains all the areas
dumped in a SYSUDUMP, plus:
1) The local system queue area (LSQA), including subpools 229, 230, and
249
2_ The input/output system (IOS) control blocks for the failing task.
The dump is formatted, so that it can be printed directly.


SYSUDUMP DD statement

i guess... The Nucleus means... core system details...

1) The local system queue area (LSQA), including subpools 229, 230, and
249
2) The input/output system (IOS) control blocks for the failing task.
